Raspberry Tart Viburnum (Viburnum dentatum ‘Rastzam’)

Raspberry Tart Viburnum

The juicy-looking Raspberry Tart Viburnum (Viburnum dentatum ‘Rastzam’) is named for its exceptionally showy raspberry-red fall foliage! Rugged and adaptable, Raspberry Tart is a striking, compact dwarf variety that produces showy flat-topped clusters of creamy white flowers in spring. These shrubs are big pollinator draws, and you’ll love seeing the ‘flying flowers’ and buzzing bees that visit your gardens!

The shiny, disease-resistant foliage lasts all summer, and then it shows off its outstanding raspberry-red color in the fall. Raspberry Tart also produces blue-black fruit which makes this a good choice for attracting birds to your yard! The textured, glossy round leaves look fantastic dark green all growing season – until fall when they’ll light up your landscape!

This compact dwarf selection is durable and hardy under harsh conditions, with superior winter hardiness! Especially cold-hardy throughout USDA growing zones 3 through 9, these are such easy-going shrubs with vibrant color, that you’ll wonder why you hadn’t purchased one sooner! For more berries for birds, plant with another Raspberry Tart or other dentatum varieties to increase pollination!

Planting and Application:

Highly tolerant of urban pollution, it will thrive in inner city environments, don’t be afraid to use these deciduous shrubs along pathways, sidewalks and the driveway where cars, traffic, and tougher conditions are often located! Line your home’s foundation with these fruity-hued flowering ornamentals and boost curb appeal big time! Pollinator gardens, cottage borders, and modern lots all become revitalized with this shrub’s fresh color all growing season long!

Ideal for use in wet soil areas that are well-drained and not stagnant, Rain Gardens and that soggy location by the gutters suits Raspberry Tart just fine! The root systems hold back soil and slow rainwater runoff, so use them atop those steep hillsides and slopes to control erosion! Perfect for colorful fall interests and creating wildlife and bird-friendly habitat anywhere without the worry that deer will munch these to the ground! These specimens are perfect for privacy, screening, property division, and space-saving backdrops throughout the landscape!

Tips for Care:

This Viburnum is a relatively low-maintenance shrub, and should only be pruned after flowering to avoid removing any of the current season’s flowers. This Viburnum shouldn’t be allowed to dry out, so provide moisture regularly and in times of need, and a well-mulched bed with 3-4 inches of arborist bark chips. Mulch not only holds in additional moisture, and slowly releases nutrients, but it also insulates the roots! Prune after flowering, as the shrub blooms on old wood. Renewal prune to remove the largest thickest stems from the ground every few years, leaving the young stems in place to flower nicely for you next spring.
